.IMPROVED-ATTACHMENT FOR WINDOW-SASH CORDS. Y

The Schedule referred to in these Letters Patent -and making part of the same To all whom it may concern t Be it known that I, S. N. CHAPIN, of New Britain, in the county of Hartford, and State of Connecticut, have-invented a new and useful Improvement. in Attaching Cords to WindowfSash and I do hereby de- Clare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this speciiication, in w ne l Figure l is a front elevation vof my invention.

Figure 2 is a side elevation of the same.

Figure 3 is a front elevation of the same, with a cord' attached. l

Figure 4 isa front elevation of the same, iu its proper position in the window-sash.

Similar letters of reference indicate like parts.

My invention consists in the use or employment of a metallic button, composed of three transverse bars, two of which are curved in one direction, and one of which is curved in the opposite direction, suiiciently to form an opening between the same, through which the sash-cord is passed and the bars flattened, thus securing the cord in the button, without knotting the .con

A designates the button, which will generally be made of cast malleable iron, but may be made of cast brass, or swaged from sheet-metal.

a c designate the concave bars, and a the convex bar.

These bars are arranged so that each bar has oppo- 'site space, in order thatthe bnttonA can be easily cast or swaged.

The button is not formed in a'trne circle, as the bars expand or lengthen in fasteningV the cord. l

If desired, a small portion of the lower side of' the button can be removed, to accommodate the loose end oi the sash-cord B.

The endof cord B is passed over bars a a' and under bar a', when the bars are flattened by a blow or.

pressure -upon them, which secures the button A firuil y to the cord B, as'shown in fig. 3.

The sash C is grooved in theusual manner, and a round hole is made at the end of the groove. v

The width of the button A should be such that when flattened, it will be equal or nearly equal to the diameter of the hole in the sash G To secure the cord B to the sash O, it'will be merely necessary to turn the loose end of the .cord

under the button A, and slip the same into its place in the sash C, when shown in fig. 4. y

By my invention the use of screws to connect the the connection is complete, as

cord tothe sash, and the-usual inconvenience of knotf4- ting the cord, are entirely dispensed with.

What I claim as new, and desire to secure byA Let-
